Answer:
417 m^2
Step-by-step explanation:
Square Pyramid Surface Area
Base Surface Area = [tex]6^{2}[/tex]
=[tex]36 m^{2}[/tex]
Lateral Surface Area =
[tex]2*3*\sqrt{\frac{6}{2}^{2}+6^{2} }\\[/tex]
=80.5[tex]m^{2}[/tex]
Total Surface Area = 116.5
Rectangular Surface Area
Surface Area = 2(6*6 + 6*11 + 6*11) = 336
336+80.5=416.5 1~417
